哈萨克斯拉夫图像文本经过行切分和列切分后,存在水平方向接触和垂直方向重叠的粘连字符。为提高字符识别率,依据字符连通域的最小外接矩形切分开垂直方向重叠的粘连字符图像块;利用判决条件:字符宽度概率密度分布图、字符图像块垂直投影的波峰数目和字符图像块垂直投影波峰的对称性,分离初始粘连字符图像块中正确的单个字符图像块和实际接触的粘连字符图像块;在允许的字符宽度范围内,寻找粘连字符图像垂直投影图的极小值点,以切分实际接触的粘连字符。实验结果表明,该方法泛化能力较好且识别率有明显提高。
哈薩剋斯拉伕圖像文本經過行切分和列切分後,存在水平方嚮接觸和垂直方嚮重疊的粘連字符。為提高字符識彆率,依據字符連通域的最小外接矩形切分開垂直方嚮重疊的粘連字符圖像塊;利用判決條件:字符寬度概率密度分佈圖、字符圖像塊垂直投影的波峰數目和字符圖像塊垂直投影波峰的對稱性,分離初始粘連字符圖像塊中正確的單箇字符圖像塊和實際接觸的粘連字符圖像塊;在允許的字符寬度範圍內,尋找粘連字符圖像垂直投影圖的極小值點,以切分實際接觸的粘連字符。實驗結果錶明,該方法汎化能力較好且識彆率有明顯提高。

After line and column segmentation of the Kazakh Slavic image text , there is adhesion between characters .To im‐prove the character recognition rate , according to the minimum circumscribed rectangle of connected domain ,the vertical over‐lapping image block of characters was cut .Decision conditions adopted included word probability density distribution of wide , vertical projection wave number ,and vertical projection wave symmetry ,those were used to separate the correct individual cha‐racters of image block and the actual contacted touching character image block .In the range of allowed characters width ,mini‐mum points of touching character image vertical projection were searched to cut the actual contacted adhesive characters .The ex‐perimental results show this method makes recognition rate improved .
